The thing I would add to your comment is that inequality in productivity is increasing. And this is actually is good reason for increasing inequality of wealth distribution. Rent-seeking, tax avoidance, buying political influence, monopolistic behavior, corruption and nepotism should go. I'm somewhat torn on the inheritance issue though. From the point of view of young children, inheritance is unfair. From the point of view of the people who worked very hard to build wealth, not being able to give it to the most important people in their lives is unfair.
